Fighting copycats variants of a piece of escaped government malware is no easy task

In the Middle East, information technology experts are grappling with a very persistent piece of malware dubbed Flame.  Flame is slightly older than the much-discussed Stuxnet worm.  Stuxnet is a researcher-named escaped variant of "The Bug", a series of worms used in an elaborate U.S. and Israeli cyber-sabotage program code-named "Olympics Games".  That effort was aimed (successfully) at destroying Iranian nuclear weapons fuel enrichment centrifuges without bloodshed.

Likewise, Flame is suspected to be written by the U.S. to target Iranian nuclear efforts or possibly Al Qaeda.  However, its goals appeared to be aimed at reconnaissance rather than sabotage.  

Regardless of the purpose, it is less subtle than "The Bug" variants, and while confined largely to the Middle East has been a top cleanup priority for Microsoft Corp. (MSFT).

On its Tech NetMicrosoft Security Response Center blog, Microsoft laid out its plans to slay Flame and harden its Windows Update (WU) process in a pair of blogs.

Microsoft reports that Flame spread itself by using cryptography weaknesses in an older version of Microsoft's certification process.  That allowed the software to pose as trusted signed software from Microsoft and install without warning the user.

In its blog, Microsoft warns, "As many reports assert, Flame has been used in highly sophisticated and targeted attacks and, as a result, the vast majority of customers are not at risk.... That said, our investigation has discovered some techniques used by this malware that could also be leveraged by less sophisticated attackers to launch more widespread attacks."

The blog goes on to reveal the company's current fix to the problem, outlining:

• First, today we released a Security Advisory outlining steps our customers can take to block software signed by these unauthorized certificates.

• Second, we released an update that automatically takes this step for our customers.


• Third, the Terminal Server Licensing Service no longer issues certificates that allow code to be signed.

II. Malicious Updates are a Harder Fix

But Flame illustrated deeper underlying security issues for Windows, in that Microsoft feared that copycats could tamper with the Windows Update process to prevent its potential removal.  Some malware authors have been finding ways to literally "turn off" Windows Update, preventing fixes and patches from reach affected machines.  And as Microsoft notes in its blog update, sophisticated attackers could even leverage Windows Update to deliver malware masquerading as signed Microsoft updates.
The dreaded restart prompt
Malware writers could potentially disguise their malfeasant wares as Windows Updates.

The company writes that it plans on "hardening" WU, commenting:

To increase protection for customers, the next action of our mitigation strategy is to further harden Windows Update as a defense-in-depth precaution. We will begin this update following broad adoption of Security Advisory 2718704 in order not to interfere with that update’s worldwide deployment. We will provide more information on the timing of the additional hardening to Windows Update in the near future.

In other words, while sophisticated state-written malware like Flame and Stuxnet may have created headaches, both diplomatically and technologically, they served as a "full disclosure" warning of sorts to Microsoft.  These attacks have given it the knowledge and motivation to patch some gaping holes that might have otherwise gone unnoticed and quietly exploited for some time -- or at least that's the glass half-full way of looking at the situation.

You could use a grammar book yourself as well.

He is totally right. MSWORD as least will give you a hint.

Not that I'm defending the practice by any means, but have you picked up a copy of The New York Times or The Wall Street Journal lately? They have just as many spelling and grammatical errors as most blogs. The days of rigid enforcement over such mundane things has long since passed.

Wow.

Don't get me wrong, I think people can be too picky about some rules - writers should have the freedom to violate some "standards" like starting a sentence with "And..." or inserting hyphens or other symbols to help convey complex meaning in non-standard ways. However, there is a significant difference between bending the rules on purpose and making simple mistakes that can change the meaning being conveyed. Those "mundane" things are there for a reason - so other people can understand what you're writing.

I find it extremely disappointing that this site seems to care so little. You apparently don't think it is very important; and Jason certainly doesn't judging by his writing. Perhaps DT should focus on doing video-blogs since you won't have to actually worry about spelling. The grammatical mistakes can be ameliorated by the tone and rhythm of your speech. Of course, someone will probably get lazy with that at some point and start pronouncing words wrong. When people complain, you can always say how "mundane" the rules of pronunciation are...

How about trying to shoot for higher standards instead of accepting the tyranny of the lowest common denominator? I am no writer - nor do I claim to be - but I at least try. This is part of your job, try and do it well.

so people should write in their mother tongue and then expect the reader to use babblefish or something like it? i would like that a little bit more of the people who were born by luck (or should say accident ?) in an anglo saxon speaking country would show some tolerance towards the people that don't have english as their mother tongue. makes me almost want chinese to become the international language and reduce 99.5 % of US citizens to international near illiterate state (just to make them see the stupidity of their arrogance). attacks on people their language skills is something i only see on english forums, never (well, at least not that i have seen) on german, dutch or french forums.

No and fewer and fewer people do. I'll give a BIG reason why in one word. Quality. I think then I will just quote you.

over such mundane things


So - obviously not important to you. I think it's a trust thing. Can I trust a reporter/blogger on what they are saying if they can't even spell it correctly? How much time and effort was involved in fact-checking if no time or effort was involved in spell-checking?

I usually don't care and glide over simple mistakes - but it is a good question I'm not sure if I've seen answered:
Is there such a thing as an editor here? Someone who proofreads an article before it is "published"?

We've long inferred that editorial content and integrity isn't a real priority here, but at least we now have written confirmation that you guys don't care about the technical quality of writing either. Thanks

It's a shame you overlooked college text books, as they are in the same league.

But what these sources don't understand is they set the bar, the done, the standard. Where else to learn the proper way, by running to an English teacher for every post?
